摘要
通过预应力混凝土空心板梁桥实桥破坏性试验,分析了这类桥梁的挠度和应变的变化规律,以及裂缝发展过程,并比较了桥梁破坏试验前后的荷载试验结果,从而为预应力混凝土梁桥的极限状态研究和承载能力评估提供依据。
Through destructive experiments on actual prestressed concrete hollow slab beam bridge, the varieties of the deflection and strain, the development of cracks of this kind of bridges are analyzed. The load test results before and after destructive experiments are compared. The results provide the basis on limit state research and bearing capacity evaluation of prestressed concrete bridges.
